Sets up a new Django project with RAPID architecture using uv. Creates horizontal layer structure with DRF, Docker/PostgreSQL support, and environment-based configuration. Use when the user wants to initialise a Django web application.

Write self-documenting code with minimal, evergreen comments that explain WHY rather than WHAT, avoiding temporary change notes or obvious descriptions. Use this skill when adding comments to any code file to ensure comments provide value by explaining complex logic, business rules, or non-obvious decisions rather than describing what the code does. Apply this skill when writing code that needs clarification, when documenting complex algorithms or business logic, or when removing outdated or redundant comments that describe obvious operations. This skill prioritizes writing clear, expressive code through meaningful naming and structure that minimizes the need for comments, ensures any comments added are helpful and explain intent or reasoning, and avoids leaving comments about recent changes, temporary fixes, or information that belongs in commit messages or documentation.

Generate and edit images using the Gemini API (Nano Banana). Use this skill when creating images from text prompts, editing existing images, applying style transfers, generating logos with text, creating stickers, product mockups, or any image generation/manipulation task. Supports text-to-image, image editing, multi-turn refinement, and composition from multiple reference images.

Detect project type and recommend deployment platform. Use when deploying projects, choosing hosting platforms, analyzing project structure, or when user mentions deployment, platform selection, MCP servers, APIs, frontend apps, static sites, FastMCP Cloud, DigitalOcean, Vercel, Hostinger, Netlify, or Cloudflare.

AI image generation and editing using Google's Nano Banana (Gemini 2.5 Flash Image) and Nano Banana Pro (Gemini 3 Pro Image) APIs. Use this skill when the user wants to generate, edit, or compose images using AI. Triggers include requests to create images from text descriptions, edit existing images, add/remove elements from photos, apply style transfers, maintain character consistency across images, generate images with text overlays (logos, posters, infographics), or create multi-image compositions. Also use when users mention "Nano Banana", "Gemini image", or want AI-generated visuals.

Debug Django REST Framework API issues including serializers, viewsets, permissions, pagination, filtering, and response formatting. Use when troubleshooting API endpoints, serialization errors, permission denials, or unexpected response data.

Generate comprehensive {node_name}.example.json files that showcase real-world usage of Workscript workflow nodes. Use when asked to document a node, create node documentation, generate node examples, or produce usage examples for workflow nodes. Also use when a subagent needs to create node documentation as part of node development or review.

This skill should be used when the user asks to "add WebSocket", "implement real-time", "create file upload", "add S3 upload", "send email", "implement notifications", "broadcast events", or mentions WebSockets, file storage, email service, push notifications, or real-time communication. Provides WebSocket, file upload, and notification patterns.

This skill should be used when setting up, managing, or troubleshooting Basilica GPU miner operations on Bittensor Subnet 39 (mainnet) or 387 (testnet).
